PORTABLE PNEUMATIC PUMPNG APPARATUS.

Application filed April i', 1910.

To ZZ l107mm 'it may Concern A lle it known that I, Howie SMALL, acitizen of the vUnited States, residingV at Atlantic itv. in the count)vof Atlantieaud State ol New Jersey, have invented Icertain new anduseful improvements in Portable .llneuuiatie Pumping' AXpparatus. oi?which the following a specification.

My invention relates to improvements in a portable pneumatic pumpingapIiara-us for el ailing earpets. draperies and the like.

The object oi luv invention is to construct a pneumatic pmnpingapparatus in whieh the housingr or easingrs form a varuum chamber and apnlsalion chamber and having a rihrating' member separatirn; saidchambers, with means for operating said vibrating member togeiher withysuitable valve mechanian. The said pulsaliou ehamber being maderelati.el.v large to form a clearance space in addition to the 4spacearually required for Jdie movements of the pumi'iing member.

A further object or' my invention to arranejethe said. chambers and theoperating means in alinement with said vibrating member.

still vlurtl'ier objet-t of my invention is to provide double connectingrods between the .'ihratinfbr member and the operatingl means; and astill further object ol my inveniion is to Connect the said vibratinginember with the eonneeting rods so aste .limit the oscillating movementot said vibrating member.

These together with various oher novel 'features of lconstruction andarrangements oli the parts eonstitute .my invention.

the hood and the screen may be lifted oil" the base l.

The hood S has a, bottom section 1% which is adapted to encircle thebase l and said hood also has a tlange 15 secured to the inner surfaceolf the same, which flange rests upon the rubber ring i6, which in turnrests upon secured to the base l. Thus making an air tight j uintbetween the hood S andthe hase.

"l" he said rubber ring lo is secured to and carried by the lower edgeof the sereen 1G. The said ring 5, secured to the base l, has formedthereon arms 17, which extend upwardly and toward the Center of he ringland terminate in the. base-plate 18, on which is/seeured the electricmotor Q0, positioned in vertical alinement with the base i and the hoodS, above described. Between the said ring and the side wall 2 of thebase is clamped a liexible diaphragm 22, preferably iliade of leather.Said diaphragm has a eireulai' opening formed in the center thereof andthe inner edge of said diaphragm 'is secured to the circular metalColl-.ir 2, which latter and the diaphragm are referred to as avibrating member. A clamping ring 24C secured to said collar 23, byscrews or other suitable, means, securely holds the inner edge of saiddiaphragm to said Collar.

The follar has oppositely positioned supports 25 and 2G in which ismounted a shaft S27, rigidly secure-d in said supports by set-serews Q8and i to the ends o1" he shaft 2T, by pins 32 and 83, and the oppositeends oi? said connecting rods embrace the eeeentrics 35 and secured uponeach end of the shaft or ture'BT ol' the motor 20. `lli/hen the shaft 3?of the motor is rotated, 'the collar will vibrate rapidly. The twoconnecting rods will hold one axis of the collar pa allel with the.motor shaft 3T and the oscillating movement of the opposite axis of thecollar will be limited by the eonneetion between the eoiiar and theconnecting rods 30 and 3l, which prevents the-flexible diaphragm L2 fromrereiving an unusual strain or from being worn in certain portions, dueto the tiliiiin;- ot the follar rlhe eollar Q3 and the bottoni 3 of thebase l are provided. in bhe Center thereof, with valves 4G and ilrespectively.
